A Reversible Data Hiding Method Based on HEVC Without Distortion Drift

摘要

This paper presents a reversible data hiding algorithm without intra-frame distortion drift based HEVC. We embed the secret information into the multivariate array of the 4 × 4 luminance DST blocks to avert the distortion drift. With the inverse operation of multivariate array in decoder, the embedded video is perfectly reconstructed as the original encoded video. Moreover, the entire process of embedding and extracting is very easy to operate. The superiority of the presented algorithm is verified through experiments.
